The advanced engineered narrow body design efficiently decreases gear abrasion, machine deformation, increases power, and extends flying durability. The unique Split-Type Main Frame design, made of composite material side plates, is engineered using our proprietary embedding technology, which strengthens the entire structure and provides better accessibility for servicing the T-REX 700X. This extraordinary design includes a progressive lightweight landing skid making the T-REX 700X the leader in the 700 class. The Align T-Rex 700X is 400g (0.882lbs) lighter than our pervious model, this can effectively increase your flight time. The brand new 700EFL Flybarless Rotor Head System utilizes an extremely low CG design which reduces resistance during 3D maneuvers while increasing flight responsiveness and precision.

The T-REX 700X is equipped with the new 850MX motor which is highly efficient with superior power, excellent torque, low current draw, and is the most advanced motor approved by World RC Champions. The new designed motor cooling mount plate can reduce the motor operating temperature up to 20°C (68°F). The helicopter’s high quality design is accented with precision machined red and silver metal parts. The brand new RCE-BL130A brushless ESC supplies extreme power. The ESC includes a superior governor and BEC which allows you to set 5V-8V (Step: 0.1V). The NEW DS820M/DS825M high voltage brushless servos are more efficient and out perform other servos in this class. To protect these servos the new high-end CNC aluminum case function as a heat sink allowing the servos to operate at a lower temperature.

We developed the ultimate perfect 700 class helicopter which is stronger, yet lightweight, and built with precision manufactured high-quality parts. The T-REX 700X, King of the Sky, has arrived! What are you waiting for? The innovative design and high-end electronics will give you an adrenaline rush!

Manufactured with durable lightweight fiber material, and utilizing an engineered aerodynamic design, the Align Advanced Lightweight Canopy forms a protective shield for the entire machine.
Landing skid is tilted 5 degree forward which improves crashworthiness.
Engineered Narrow Body Design efficiently decreases gear abrasion and machine deformation. The Align T-Rex 700X newly designed narrow body is more powerful and has longer flying durability.
The 700EFL Flybarless Rotor Head System utilizes extreme low CG design to effectively reduce resistance during 3D maneuvers while increasing flight responsiveness and precision. In addition, the high quality of the helicopter design is accented with red anodized and stainless color precision machined metal parts.

Align Advanced Metal Swashplate firmly connects to rotor grips preventing rotor head disengagement during intense flight. Two linkage ball mounting holes provided to improve control of system movement. A resolution hole or larger movement reaction hole can be selected based on your flying preference or style.

Our new 850MX motor inherited features from the previous 800MX such as high efficiency, superior power, excellent torque, low current draw, and a low operating temperature. The 850MX is capable of maintaining a more consistent torque and head speed through continuous 3D maneuvers. This is a particularly designed for 3D flights.

The CNC Plate is designed to strengthen the Align 700X frame while efficiently acting as a heat sink to efficiently dissipate motor heat. (This can lower motor temperature up to 20 degrees Celsius during flight)

3K Main frame features; embedded battery mounting rails, integrated magazine structure, and a latch design. The CNC Aluminum Battery Mount provides great protection for the battery while providing a convenient way for mounting.
Composite material side plates engineered by exclusive embedding technology, which strengthens the entire structure and eases serviceability.

Integration of CNC Aluminum alloy and POM Polyacetal which can lower friction between the linkage ball and the Metal Anti Rotation Bracket. In addition, this new design increases the efficiencies and accuracy of the servos.

Highly enhance structural strength, effectively increase the torsional capability.

Brand new matting carbon tailboom using carbon fiber and aluminum imbedded technology, features light weight and high strength.


A simple enhanced Multiple-bearing design allows smooth and accurate movement. Take control of your T-Rex 700X just the way you like it!
